2、nd biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural field equipment, farmstead equipment, structures, soil and wat

3、er resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advisory only. Their use by anyone eng

Conformity does not ensure compliance with applicable ordinances, laws and regulations. Prospective users are responsi

ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE”, regardless of the revision approval date. Newly developed Standards, Engineering

6、 Practices and Data approved after July of 2005 are designated as “ASABE”. Standards designated as “ANSI” are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verification by ANSI that the requirements for due process, consen

7、sus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but n

8、ot necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE require that action be taken peri

9、odically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. AIl rights reserved.

Keywords: Drawbar, Lawn, Power take-off, Tractors 1 Scope This International Standard specifies the dimensions and location requirements for drawbars on lawn and garden ride-on (riding) tractors. It applies to lawn and garden ride-on (

15、riding) tractors as defined below. The requirements specified are essential to ensure that all types of towed implements, designed for operation in conjunction with lawn and garden tractors, can be operated with all currently manufactured types of lawn and garden tractors designed to pull such imple

16、ments. 2 Definition For the purposes of this International Standard, the following definition applies. ride-on (riding) machine; lawn and garden tractor; turf (riding) tractor: Self-propelled machine on which an operator rides, designed primarily for cutting grass and auxiliary garden work. The cutt

17、ing means may be an integral part of the machine or suspended from or attached to the machine.13 Dimensions The drawbar, both of the tractor itself see Figure 1a) and of the implement see Figure 1b), shall be rectangular and shall have the dimensions given in Figure 1 and Table 1. 4 Location The dra

18、wbar shall be located on the longitudinal mid-plane of the tractor. 1For the convenience of the user of this International Standard, this definition is repeated from ISO 5395:1990 (definition 1.3.40).
